Trader consensus centers on a 27°C minimum for Shanghai on August 21, driven by real-time station observations and short-range forecast models showing overnight lows holding steady near that level under typical late-summer subtropical conditions. Persistent high pressure and weak synoptic gradients have limited nocturnal cooling, consistent with regional climatology where August minima cluster between 26–28°C absent frontal intrusions. Official monitoring networks report no significant model divergence on this threshold. An unexpected cold-air advection event or measurement adjustment at primary sites could realistically push the outcome to 26°C, though current atmospheric patterns make such shifts improbable before resolution.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the Shanghai Pudong International Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Shanghai Pudong International Airport Station, available here: https://www.wunderground.com/history/daily/cn/shanghai/ZSPD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Trader consensus centers on a 27°C minimum for Shanghai on August 21, driven by real-time station observations and short-range forecast models showing overnight lows holding steady near that level under typical late-summer subtropical conditions.
